There has been a lot said about AGK2 3D so I have made my 1st 3D App to try out what's available at the moment.
Although I have used very basic shapes there are clearly still a lot of possibilities with 3D.

My game is MemoryCubes, being a variation on the popular "pairs" card game, i.e. select 2 cards to see if they are a matching pair.
Using 2D you are quite limited to the number of images that can be laid out to select your pair from, but using 3D cubes gives you 6 x the capacity. Simply rotate the cube to reveal more faces to choose from.
